The Moon Cerberus Rechargable Rear Light combines the technology of the Moon Comet X (Now with three LED strips) into a 270 degree performance light. It's ideal for road bikes as it can fit all styles of seatpost including aero shaped posts. Weighing just 35 grams it can be used as a daytime running light or for added visibility at night.

That light may run 500 or 600 lumens for 2 or 3 hours. So it's worth buying a light with more lumens than you need to get decent running times.
